SPECIFICATION forming part of Letters Patent No. 739,143, datedSeptember 15, 1903. Application filed January 31 1903. Serial No.141,292. (No model.)

T0 at whom it may concern:

Be it known that LJACOB L. BERGE, a citizen of the United States, and aresident of Minneapolis, in the county of Hennepin and State ofMinnesota, have invented new and useful Improvements in Oil-Stoves, ofwhich the following is a full, clear, and exact description.

This invention relates to certain novel and useful improvements inoil-burning stoves.

I have particularly in View as an object the provision of a stove whichshall have an oiltank arranged compactly therein and a chamber or casingarranged above the tank and provided with apertures or passages to allowair to pass through said chamber, such air being heated in its passage.

A further object of the invention is to provide an improved arrangementof conduct: ing tubes or ducts for carrying ofi the products ofcombustion from the burner.

A further object of the invention is to pro- 'vide a stove which will beexceedingly simple in its construction, one which may be manufacturedand sold at but comparatively small cost and at the same time shallembody the essential features of cleanliness, safety, and convenience.

To the accomplishment of the above-recited objects and others of asimilar nature in view my invention consists in the construction,combination, and arrangement of parts, as is described in thisspecification, delineated in the accompanying drawings, and set forth inthe appended claims.

. Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference-indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of a stove embodying my improvement. Fig. 2is a central vertical sectional View taken through the same on the line2 2 of Fig. 3. Fig. 3 is a transverse sectionalview taken on the line 33 of Fig. 2, and Fig. 4 is an enlarged detail vertical sectional view ofthe burner portion proper of the lamp.

Referring now to the accompanying drawings, 1 designates the baseportion or housing of the stove, which is adapted to be elevated 1slightly from the floor and supported bya suitable number of legs 2. Ofslightly less diameterin cross-section and arranged in the aforesaidhousing 1 is the chamber 3, adapted to contain fuel, which preferablyconsists of oil or a suitable hydrocarbon liquid, as shown at A. Thebottom portion of the base housing or chamber, which also forms thebottom of the oil-chamber, is apertured to permit the passage of theair-pipe 4, provided with a controlling-valve 5. Thispipe is ofpreferably elbow form-that is, has a horizontally-extended portionand isbent to extend vertically upward through the oil-chamber, as at 6.Mounted above the portion 6 of the tube is a perforated cap 7, having arelatively large flat plate 8, covering the same. Spaced apart from eachother below the plate are a number of annular flanges or rings 9, whichact as deflectors or flame-regulators,'the lowermost of said rings beingadapted when the cap is turned to act as a wick-cleaner. The rotation ofthis cap is accomplished by means of a spindle 10, which extendsvertically upward from the elbow of the air-tube and through the cap,the lower portion of said spindle 10 being provided with interrneshinggearing 11, whereby it is connected with a rod 12, extending out throughthe air-tube near the base portion of the stove and provided at its endwith a thumb-wheel 13. It will therefore be seen that when the rod 12 isrotated or turned the vertical intermeshing geared spindle will also berevolved, and the cap being rigid with the spindle will revolve. Thewick (shown at B) extends around the air-tube and is in turn surroundedby a wick-supporting tube 14:. To the side of this wick-tube is secureda serrated bar or rack 15, which intermeshes with a pinion 16, rigidwith the inner end of a turning rod 17, said rod having athumb-wheel18'at its outer end. As will be seen,'especially by reference to Fig. 2,this rod extends through a frusto-conical plate-like portion 19, whichacts as a diaphragm and divides the portion of the stove containing theoil-chamber from the upper or casing portion thereof, said platelikediaphragm having a flange 20, formed circumferentially thereof, whichacts as a hearing or seat for the main casing 21 of the stove. The topof the oil-chamber, which is shown at 22, is also slightly convexedinshape, and at its apexor center is provided with a backwardly-turnedhead or rim 23, adapted to interlock with the inwardly extendingshoulder 24: of a collar 25, the upper shoulder 26 of said collar beingscrew-threaded to the" outer surface of the thimble 27, the side 28 ofsaid thimble bearing against the wickholding tube 14. As will beobserved in Figs. 2 and 4, this thimble is provided with rows ofcircumferentially-arranged apertures 29.

The upper portion of the stove comprises the casing 21, mounted upon theshoulder 20 of the diaphragm 19, the said casing being provided with acover of any suitable character, such as shown at 30. Arranged withinthe body portion of the casing are a number of approximately parallelvertical tubes 31, which are incased between the outer wall 21 and aninner wall 32, arranged so that a space of sufficient size toaccommodate the tubes 31 extends circumferentially between the inner andouter walls. The height of the inner wall is less than that of the outerwall of the casing, and the top portion of said wall is provided with aflange 33, which extends horizontally outward and abuts against theouter wall or casing. This portion 33 is provided with apertures forpermitting the pipes to extend therethrough, and above the same Ipreferably arrange two partitions 34 and 35, approximately parallel andspaced apart, such partitions being also provided with apertures topermit the passage of the upper ends of the pipes or tubes 31. The upperand lower ends of these tubes 31 are open, and at the lower end of thecasing a passageway 36 is formed, through which passage flow theproducts of combustion of the wick or burner, such products passing upthrough the vertical pipes 31 and out through an opening 37, arranged inthe outer wall of the easing between the cover and the upper partition35.

At the back of the stove or casing I have arranged a number of air tubesor ducts 38, which communicate, as at 39, with the space formed betweenthe partitions 34 and 35, and such air after being heated in its passagethrough the space between the partitions is allowed to escape at 40 intothe room. I have also provided a row or a number of apertures 41 nearthe bottom of the casing 21, through which apertures air enters andbeing heated in its passage through the flueway by the pipes 31 thenescapes in such heated condition through similar apertures 42, arrangednear the upper end of said casing.

If desired, anysuitabie device, such as that shown at C, may be placedin the oil-tank for the purpose of indicating the amount of oil therein,an indicating arm or rod extending outward through the casing and havinga pointer, as at D, at the end thereof.

From the above description, taken in connection with the accompanyingdrawings, the construction and operation of my improved burner or stovewill be readily apparent. The wick being lighted, a suflicient amount ofair is admitted through the main airtube and the section 6 thereof tothe burner to enable the same to burn freely, and the products .ofcombustion from the wick or burner pass upward through the verticalpipes 31 and escape at the opening 37. In the meantime the air which isadmitted through the tubes 38 and through the orifices 41 is heated andescapes in such heated condition into the room or apartment through theair-outlets 4.0 and 42. I

While I have shown and herein described one particular embodiment of myinvention, it is of course to be understood that I do not limit myselfto the precise details of construction, as modifications and variationsin some respects may be made without departing from the principles ofthe invention or sacrificing any of theessential features thereof.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1.
